Linear Regression Model

Model equation:
Yi = α + β × Xi + εi

Top border of price channel:
Exp(Yi) = Exp(a + b × Xi + 2 × s)

Bottom border of price channel:
Exp(Yi) = Exp(a + b × Xi – 2 × s)

where:

i - observation number
Yi - natural logarithm of FIZZ price
Xi - time index, 1 day interval
σ - standard deviation of εi
a - estimator of α
b - estimator of β
s - estimator of σ
Exp() - calculates the exponent of e


Primary Trend

Start date: February 2, 2021
End date: June 26, 2024

a = 3.7425

b = 0.0000

s = 0.0791

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × 0.0000) – 1
= 1.52%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.0791) – 1
= 37.21%

February 2, 2021 calculations

Top border of price channel:

Exp(Y383)
= Exp(a + b × X383 + 2 × s)
= Exp(a + b × 557 + 2 × s)
= Exp(3.7425 + 0.0000 × 557 + 2 × 0.0791)
= Exp(3.9237)
= $50.59

Bottom border of price channel:

Exp(Y383)
= Exp(a + b × X383 – 2 × s)
= Exp(a + b × 557 – 2 × s)
= Exp(3.7425 + 0.0000 × 557 – 2 × 0.0791)
= Exp(3.6074)
= $36.87

Top border of price channel:

Exp(Y1,237)
= Exp(a + b × X1,237 + 2 × s)
= Exp(a + b × 1,797 + 2 × s)
= Exp(3.7425 + 0.0000 × 1,797 + 2 × 0.0791)
= Exp(3.9750)
= $53.25

Bottom border of price channel:

Exp(Y1,237)
= Exp(a + b × X1,237 – 2 × s)
= Exp(a + b × 1,797 – 2 × s)
= Exp(3.7425 + 0.0000 × 1,797 – 2 × 0.0791)
= Exp(3.6587)
= $38.81

a = -0.2041

b = 0.0023

s = 0.0413

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × 0.0023) – 1
